日劇增，城市里尤其突出。在部分實驗結(jié)果我們驗證了這一過程。所有模糊規(guī)則，包括優(yōu)化周期時間和相位類型的規(guī)則，在這個過程中，準(zhǔn)備以調(diào)查問卷形式和展現(xiàn)給一些專家包括從德黑蘭警察局交通上校和兩名來自德黑蘭的交通組織工程師。因此，平日的隸屬度比假期多。另一種模糊的規(guī)則類別涉及估計優(yōu)化周期時間。在第6節(jié)，智能系統(tǒng)的運作被完整描述，最后在第7節(jié)對所提出的方法進行評估，對結(jié)論進行闡述。本文的目的是介紹一個紅綠燈有效控制孤立交叉口這方面的知識重用的控制本體。全面知識建模領(lǐng)域的一個最合適的方法是使用本體概念。通過這種方式，增加軟件的獨立性和為其他的軟件開發(fā)活動如測試和維護，提供了便利。結(jié)果表明，在擁擠的交通條件下，聚類控制器性能優(yōu)于其它所有測試的非自適應(yīng)控制器，我們也測試?yán)碚撋系钠骄却龝r間，用以選擇車輛通過市區(qū)的道路，并表明，道路使用者采用合作學(xué)習(xí)的方法可避免交通瓶頸。在研究中，我們著重于微觀模型，該模型能模仿單獨車輛的行為，從而模仿動態(tài)的車輛組。在世界范圍內(nèi)，一個以微電子技術(shù)，計算機和通信技術(shù)為先導(dǎo)的，一信息技術(shù)和信息產(chǎn)業(yè)為中心的信息革命方興未艾。隨著大規(guī)模集成電路及計算機技術(shù)的迅速發(fā)展，以及人工智能在控制技術(shù)方面的廣泛運用，智能設(shè)備有了很大的發(fā)展，是現(xiàn)代科技發(fā)展的主流方向。但是，智能交通控制的應(yīng)用還存在局限性。等待，直到車輛到達目的地，通過有聚類算法的基礎(chǔ)設(shè)施，最后經(jīng)過監(jiān)測車的監(jiān)測。Every crossing has the fixed duty period,charges centrefor being able to change it’s period and in depending on a road when being crowded。比較結(jié)果顯示：在所有的交通條件下，在每個周期中，對每輛車它有低得多的平均延遲時間與其他的控制系統(tǒng)相比。在近年來，本體論上的研究正成為一個新的熱點話題在不同的活動，如人工智能，知識管理，語義網(wǎng)絡(luò)，電子商務(wù)和幾個其他應(yīng)用領(lǐng)域。在第3節(jié)，新的系統(tǒng)架構(gòu)是基于分層語義網(wǎng)絡(luò)架構(gòu)。有幾層語義Web的建議源自伯納斯滯后階段。圖5顯示日期，時間和周期時間的隸屬函數(shù)。此功能是使用專家的意見。由于邏輯交通控制已建成的基礎(chǔ)上，如指定要求優(yōu)化循環(huán)時間，逐步淘汰型，交通的移動和優(yōu)化綠燈時間，每個階段的序列中，第一項活動是最好的結(jié)果。因此，設(shè)計好的超聲波測距儀就顯得非常重要了。二是被動式安全技術(shù)，即事故發(fā)生后的乘員保護。奔馳汽車公司對各類交通事故的研究表明：若駕駛員能夠提早1S 意識到有事故危險并采取相應(yīng)的正確措施，則絕大多數(shù)的交通事故都可以避免。這些產(chǎn)品存在的主要問題是測量盲區(qū)大，報警滯后，未考慮汽車制動時的慣性因素，使駕駛者制動滯后，抗干擾能力不強，誤報也較多。完成這種功能的裝置就是超聲波傳感器，習(xí)慣上稱為超聲波換能器或超聲波探頭。利用超聲波檢測距離，設(shè)計比較方便，計算處理也較簡單，并且在測量精度方面也能達到要求。中原工學(xué)院畢業(yè)設(shè)計（論文）譯文
